innovation of reciprocating torque
actuators. Its interior design and construction
are similar to standard lines
of stationary actuators, but the
Rotating actuator, unlike the stationary
models, revolves in application. Also,
its applications are entirely different.
It consists of an aluminum alloy
body with a precision machined
cylindrical chamber, a central splinedend
shaft on which vanes are fixed, and barriers or shoes that provide
positive internal stops for the vanes. The number of vanes and shoes
within the unit limit the arc of vane travel and effect the torque output
capacities.
Power is derived from either hydraulic or pneumatic pressure directed
against the vanes which, in turn, rotate the splined shaft. Although the
shoes limit the movement of the vanes to a precise maximum degree, any
required arc of movement can be controlled by valves and external
positive stops. Infinitely variable, increasing and decreasing, and sudden
loads can be applied.
Reciprocating torque actuators, like most power outputs, are usually
mounted to a stationary base. But the Rotating actuator revolves in
application as an integral part of a functioning device: the body, vanes,
and shaft rotate in unison, maintaining their relationship until fluid
pressure changes the position of the vanes.
